Your article is a good one, but the tone towards RV's and living in campgrounds is oddly negative.

>>An RV is basically a house on wheels and isn’t particularly inexpensive or minimalist.

Our was pretty inexpensive, is more minimalist than most US based folks and will hold its value just like the camper vans you mention.

>>If you pay to stay at a campsite, it’s most certainly legal, but then this lifestyle ceases to be inexpensive.

$25-$30 a night is most certainly cheaper than most mortgages or apartments.
Heaven forbid they spend 10 dollars on a php upload script on SSL for this kind of information as opposed to "Scan you social security card and send it to customerservice@airbnb.com!"
Google has a search algorithm that outperforms any other. Their value proposition is that they can help you find what you are looking for better than their competitors can. Amazon has a vast network of suppliers and infrastructure. Their value proposition is that they can provide better selection and delivery than their competition. In both cases, the value is provided by the company.

Facebook is a website that lets you share text and images with your friends. Their only value proposition is that they have a lot of customers: the value of facebook is not provided by facebook. What makes them valuable is simply inertia, and if they lose that inertia they are dead. They have no technical advantage to the competition.
I have both the X220 (standard kb) and X1 (chiclet kb). The X220 keyboard is much better than the X1.

My brother did this exact same thing (competing with his friend to try to make as many folders as possible), only he got a 1 week suspension for "hacking". The IT manager was really pissed and pressed the school administrators to make an example out of them.

I was outraged. Basically, the IT manager preferred to use punishment as his means of security, rather than actually doing his job.
Crypto-newb question: is there any reason it takes the "number of computations" difficulty as a given, rather than estimating the rate at which attacks will get smarter and require fewer computations?

The analysis that's given includes estimates of decreasing computation cost from Moore's law, but no corresponding estimate of decreasing cost from patterns found in the SHA-1 hash function.

Also, why does the cost estimate focus on commodity CPUs, rather than GPUs, which are much better at the (parallel) computations that hash attacking involves?
Tynan lives in his van RV in SF and works on his startup full time. He's been living in it for years. If I was going to do this, I would get a roadtrek and remove the decals. They stand out the least.

Apple Alumni And How They Went On To Change The World
Worth mentioning here that practical collision attacks do not automatically jeopardize all security protocols that depend on the hash. For instance, MD5 is totally broken, but there are no known practical attacks against HMAC-MD5. I hope it goes without saying that this stuff generally does not apply to password hash constructs either.
It devours everything it touches and produces nothing of value, including—ironically—their stock price.

It produces something of value to me. I live in CA, my parents live in NY. We're in different worlds. I can't possibly communicate what my world is like to them via a daily phone call. But I can share bits and pieces of info on Facebook that they see, and it's a wonderful medium for us to have shared experiences for things that otherwise would be extremely difficult to share.

It's a new mode of communication. Without it, I'd be alienated from my friends and family across the continent and in a few years we would have easily grown completely apart. With it, when I go back to visit, it's as if I never left. I can actually exchange pictures with my grandparents, and they can actually be a part of my life every day. Facebook seriously impacts the direction of my life, with respect to family and friends.

One billion people realized this, consciously or unconsciously, and made Facebook a multibillion dollar company. At this point saying Facebook produces nothing of value is as delusional as saying that about Microsoft, or Apple, or Proctor and Gamble.
I did all 2 of my academic projects in my college itself, while many others did outside.
You my dear chap make a lot of sense. (really)

I don't know about OP, but I've always assumed that by 2012 people would have the common sense to ask their landlords first for permission (either one time or recurring). I haven't listed on AirBNB but have sublet my apartment and that was obviously step one. Are most of the people using the site not doing that?
I think what you're recommending is called a trailer park. A trailer park with a very strict community guidelines.
I think u r right. not many are business owners. I did my academic projects myself and now an entrepreneur.

This glorifies the bag tag a little too much. The bag tag is part of a solution that is only as good as the information supporting it. Airlines are still running archaic backend systems (e.g. systems from the 70's in some cases) & error-prone human processes that simply do not reliably collect and deliver proper baggage information to baggage systems. You would be shocked by the percentage of bags that cannot be processed because the baggage messages are simply not recieved (nevermind format errors, missing fields, etc.).

RFID solutions only improve read rate and tracking while the bag is on mechanical equipment, but do not address issues with manual handling at various other steps (e.g. moving bags from delivery piers to carts, and then to planes). And RFID does not address the information quality problem. That's partly why RFID has only been implemented in a handful of airports (e.g. HK & one of Milan's terminals) despite being feasible for a decade.

To truly reduce baggage losses, airlines & airports need to work together and implement multiple solutions that track and improve performance end to end - for all automated and manual processes.

Disclosure: I worked on designing & enhancing baggage systems for a common-use airport that is consistently ranked in the top 10 by awards (e.g. http://www.worldairportawards.com/).

The probably don't really care. It's just some CYA forced on them by their insurance company.
Perhaps, but Windows's is a bit too low.
I have never understood this either. These procedures must be a relic from a time when most people did not have access to laser printers.

Similarly when I went to renew my drivers license, they required proof of my social security number. My old license (with a picture of me, holograms, etc.) wasn't acceptable, but a health insurance card that could have been printed by anyone with access to a laminating machine was perfectly fine.
Have you researched hostels? They're still not cheap by the standards of developing countries, but when I stayed in SF a few years ago, a bed at a hostel could be had for a fifth of what a hotel would have cost me, and certainly beats sleeping in a car. On the other hand, I found food shockingly expensive, and I come from Germany.
In the article, near the end, they suggest that scientists are looking into alternatives that work like Ketamine, but so far none work as fast as K.

"Efforts to develop drugs that replicate the effects of ketamine have produced some promising results, but they do not act as quickly as ketamine. Researchers are investigating alternatives they hope can duplicate the efficacy and rapid response of ketamine."

So my question is, why not just administer K?
I spent two years driving from Alaska to Argentina, feelancing website design and code along the way.

For the entire trip, my monthly expenses were less than they were in the 2 years prior just going to work every day. Yes, that includes gas for 40,000mi.
I lived in my Jeep/tent the entire way.

I plan on doing something similar (but bigger) again, and I'll be building a more livable vehicle with a sink, stove, fridge, better sleeping, etc. etc.

AFAIK GPUs are far more cost effective. I've just produced this estimate.

2xAMD 7970 : 8000Mhash/s ~= 2^33
Seconds per year ~= 2^24
Total Hashes ~= 2^57

1kW * $0.15/kWh * 1 year ~= $1315
Rig cost (guess) ~= $2000
Total cost ~= $3315

Price for 2^60 hashes in a year:
2^60 / 2^57 *	$3155 ~= $25000

If you assume a	6X discount in 2021, then it will be <5k. Still, it takes a year, or more money for machines. Corrections welcome. Trying to run sixteen 7970s for a year straight is probably a total crap shoot.

The hash rate is from http://www.codinghorror.com/blog/2012/04/speed-hashing.html .

[EDIT: I wouldn't be shocked if FPGAs could do it with 1/10th the power and heat, with the same variable cost (hardware & power) but with an additional fixed cost to build the devices; I'm basing this estimate on bitcoin mining boards like these:

The thing I find myself hating about all of these anti-Facebook rants is that they all seem to operate under the assumption that Facebook has "subsumed" all of this functionality from the internet at large, which seems spectacularly false.

The number of people who "switched" from doing all of these things (blogging, IM, photo-posting, online gaming) on other sites to using Facebook for them is a tiny tiny minority compared to the number of people who never did any of them before.

It assumes that if Facebook went away, that all of these people would just go "back" to using Blogger, or Flickr, or AIM, or Armor Games, and the internet at large would be a better place.

I don't think that's even remotely true. Nerds can happily continue to use those services, and regular people will keep using Facebook.

Sure, someday there'll be a "new Facebook", and then people can complain about that walled garden.

People whining about Facebook feels very much like people whining about American Idol (or stupefying-ly popular CBS sitcoms). Like if 2.5 Men was suddenly cancelled, people would all start watching Mythbusters or assembling Arduinos.

Providing "free" online services to a billion people seems like a giant win for society.
It's just that in our field seniority doesn't give you such an enormous advantage as in other fields. is the opposite of my experience.

Well perhaps you are drawing the distinction between seniority and experience. There are likely some folk who have programmed in cobol as long as I have been programming. Unlikely they have equivalent experience.

The more things that I learn that don't work, the more value I offer to my clients/employers/colleagues.
Juking Your Facebook ‘Share’ Stats Is as Easy as Sending a Message
He's only providing a lower bound for this numbers, he specifically spells your concerns. He mentions that any improvement on:

* number of cores per CPU

* number of CPUs per server

* any improvements in cryptanalysis

* instruction set improvements (arm sha1, gpus)

Will only make his number even scarier.
Yes, totally obvious. Would have been more interesting if any of those results hadn't been completely expected.
I'm 43. I concur Mr. Wulf that "large scale, high stress coding" is "a stupid person's game". Now, some people find a thrill in coding under pressure. More power to 'em. Yet we see too many developers accidentally ending up in high stress coding situations and thinking that is the norm and accepting it as their fate. There is no reason it should be this way. Professional programming should be and can be fun, enjoyable, creative. As Mr. Wulf states, our profession offers an unusually wide variety of projects, tools, teams, and working environments.

Choose poorly from among this variety and you'll burn out. Choose wisely and you'll have a long, enjoyable career with plenty of extra mind and body capacity for other interests. It's up to you.

There are supposed to be checks in place to stop things like credit card theft from having an immediate affect though.

> Cashiers should be asking for ID and checking your signature. It's actually a control that is supposed to occur in stores.

No, it's not. For small purchases, merchants are not required by the credit card companies to check ID or to even ask for a signature.

And for larger purchases, it typically still doesn't happen. My credit card has "ask for photo ID" written on the back instead of a signature. Even with this, I get asked for ID maybe once every two months. Checks that are supposed to happen don't matter. Only checks that actually happen matter.

> Someone grabs your phone and gets free meals? What controls are there on that interface?

Well, if you're using the system Dorsey was describing, your photo pops up every time you go to pay. So the cashier sees it without asking for it. So if I try to pay with your phone, the cashier can say, "I'm sorry, but you don't look much like rbellio. Should I call my manager over?"
Why Did the U.S. Abandon the Gold Standard?

That was how RSA was breached, which led to the eventual loss of the SecureID master key (and follow-on breeches at DoD suppliers).
Calm down mate, I'm merely disagreeing with you. I do understand your point, and I do think that your interpretation makes for a reasonable hypothesis, but it's my opinion that it's less plausible given the exact wording originally provided.
So we have someone who didn't play his guitar because it was in another room. And someone who spent 3 hours per day watching a sitcom on netflix. And you wonder why he is living in a van?

Watching Netflix for a few hours in a row and having an instrument you don't play as much as you should are incredibly common experiences. I don't know how you extrapolate that into some sort of mental illness or moral failure that leads to living in a van. I don't think he was literally too lazy to go to another room to play his guitar. It's just a way of saying that when you have a big house and a lot of stuff you can lose track of things you used to find important and fulfilling.

I am in no way an official spokesperson for them, just a developer, I don't know how much publicity I am allowed to draw to our back end architecture without getting into trouble.

You might want to check the zoning laws for your area too, that's another potential legal problem for this kind of thing.
Right. I get that.

Your parent comment implies they would have an "energy alternative" to... energy.

When you say "A civilization so advanced as to be able to capture the entire energy of a star, probably also has energy alternatives".

What "energy alternatives" are you talking about?
The bigger the file size, the larger the chance that it has been generated in a pseudorandom way, meaning it is in theory compressible.
On the flipside, in a larger file finding patterns from that pseudorandomity could take longer.

Yes the scale is closer to lumens than watts, but more people probably know what a watt is so I used that.

Anyway a lumen is just a way of weighting different wavelengths, and the magnitude scale uses a different way of weighting, so it's not lumens.
<<Inflation is really no worse than taxation ... An objection to inflation is an objection to tax a priori; which is fine, I simply ask for an awareness that the two items come as a package.>>

Which is the point Libertarians are trying to make! Taxation is theft according to libertarians. Inflation, like taxation, is theft. You actually ended up agreeing with them by saying that inflation is no worse than taxation. To libertarians, tax and inflation are both theft.
Putting money into a house you'll presumably be able to live in rent-free once it's paid off may not be a drastically worse choice than putting your money into savings. Unless it was an impractically huge house, or otherwise somehow not a keeper, I wouldn't consider that a frivolous/non-frugal purchase.

Take a look at how many articles on the frontpage today today don't follow those principles.

For instance the current #1 post - "Living in a van" - has one mention of Priceonomics in the article, no explanation of the service, and no call to action within the story content.

Not saying that this isn't obvious, just saying that despite it being obvious people don't necessarily employ those strategies and are tossing out a huge number of potential new users as a result.

What is the use case for this? At best, I could see replacing data with something with the same hash but is gibberish. Why would a "crime syndicate" want this?

Also wouldn't an n-tuple of multiple hash methods and the file size be even more impossible to replicate than a single hash, but not be that much harder to generate initially?
Note that I've made all of my main points in the first sentences of what I've written. Did you even read everything, or did you just scan through and pick up on a few words? The attention paid to each line decreases exponentially as you continue.

On the other hand any loan to a small business is automatically risky, looking at the failure rate. I would hate for small businesses to be unable to get money.
I agree with you.

The one thing I can never figure out is why managers of some types of companies run them the way they do. Why couldn't a call center employee work with a headset from a van and wear whatever they please? There's all sorts of strange practices that some of these companies do. Never in a million years would I ask an employee to submit to a drug test before being employed for example- yet that's what things like call centers do.

I want my employees to be happy, because they are the people that make the company work. When I talk to a manager of a company like this - they act like I've never managed anything before and just 'dont get it'.
Code is Creative
Great advice for other startups trying to exploit HN for traffic!
It is impossible to estimate decreases from "patterns found in the SHA-1 hash function". There is a good likelihood no patterns will be found in 10 years. It is also possible (although probably unlikely) an attack could be found that utterly breaks SHA-1.
You're not allowed to talk bad about apple here. Enjoy your shadow ban.
I can't answer why GPUs weren't considered, though I'd guess because they weren't as familiar with the numbers and this was a "back of the envelope" calculation.

The reason why I wouldn't take into account better attacks is because that's much harder to predict than Moore's law. Also, this is supposed to be more of a worst case scenario, so even if no advances are found it will cost at least that much.
GPU's are obviously more cost efficient than general purpose x86 CPUs. But as we are learning, specialty hardware using very little power can be an extremely effective hashing device hash as butterfly labs is doing with SHA-2[1]. If a similar device were developed for SHA-1, I'm not crypto-proficient enough to know the difference, but I imagine it would be extremely efficient as well.

This would be why the ycombinator startup churner is bad. It is entirely focused on having people with no technical skills create companies that rely very heavily on a solid technical foundation. My 8 year old knows not to send sensitive information over unencrypted channels, and that email is completely insecure. Why are people who don't know this making sites like airbnb?
I think we can assume that governments are capable of cracking SHA-1 today, and all common internet encryption protocols like AES-128 last year. The costs of building such a facility would be trivial and could be hidden within almost any TLA agency's budget.
